Comment:

 This bug still exists as described in the original post. I've tested with
 Boost 1.45 but I believe it's still there in 1.47.

 The regular expression "(?i)[dh]og" should match on both "HOG" and "dog"
 but in fact only matches on "dog". Please see the attached sample code
 boostbug698.cpp.

 I've fixed the bug as follows: at boost/regex/v4/basic_regex_creator.hpp
 line 1216 change m_icase to l_icase.

 {{{
 < if(&c != re_is_set_member(&c, &c + 1,
 static_cast<re_set_long<mask_type>*>(state), *m_pdata, m_icase))

 > if(&c != re_is_set_member(&c, &c + 1,
 static_cast<re_set_long<mask_type>*>(state), *m_pdata, l_icase))
 }}}
